Cloning a Subgraph and later Merging it back to the source graph

Hello guys!

I am creating a Graph and I Clone a few SubGraphs out of it. Pretty straight forward. But how about merging or applying the graphs back to the source graph?

For example I have a graph and I clone a SubGraph out if it. After that I make some modifications to both the source and the cloned graph (changing properties, relations etc). How would I go about applying the changes that happened in the cloned graph back to the original one and keeping the differences at the same time?

Is this something available out of the box or will it require a custom implementation?

Thank you very much for your time and all best!
